(Summary description)Water fee: 5 yuan per party, electricity fee: 0.8 yuan per kWh, equipment model: 20 tons per day The ice cost of direct cooling block ice machine is as follows: Water fee: the equipment makes 20 tons of ice a day, and the water fee per day is 20*5=100 yuan Electricity cost: The electricity consumption of direct cooling ice making is about 60 degrees, here is calculated at 65 degrees, the electricity cost: 20*65*0.8=1040 yuan Labor: labor is calculated at 25 yuan per hour, 2 people, each person works 4 hours a day, labor cost is: 2*4*25=200 yuan The cost of brine type block ice machine ice is as follows: Water fee: The equipment makes 20 tons of ice a day, and the water fee per day is 23*5=115 yuan (Salt water generally costs more water, 20 tons of ice and 23 tons of water are just estimates) Electricity cost: direct cooling ice making consumes about 80 degrees, here is calculated at 85 degrees, electricity cost: 20*85*0.8=1360 yuan Labor: labor is calculated at 25 yuan per hour, 2 people, each working 6 hours a day, labor cost: 2*6*25=300 yuan The cost of buying salt: the 20-ton ice maker runs for 8 months every year, the cost of buying salt is about 4000 yuan, and the cost of buying salt: 4000/240=16.7/day Note: The salt water concentration will decrease due to repeated ice production, and salt must be added to the salt pond to maintain the concentration. Generally, calcium chloride is purchased, and the market price is 1,000 yuan/ton. Ice mold replacement fee: 20 tons of ice mold and ice bucket holder, the total value is about 50,000 (protection replacement labor, freight, etc.), the equipment is calculated at 6 years, the ice mold replacement is: 8,300 yuan a year, every year Calculated based on 8 months of ice making, the daily cost is: 8300/240=34.5 yuan Note: The direct cooling type ice mold basically does not need to be replaced, and there is no need to buy salt, so the cost is lower. Therefore: the direct cooling block ice machine costs 20 tons of ice per day: 100+1040+200=1340 yuan The cost of making 20 tons of ice per day for the brine type block ice machine is: 115+1360+300+16.7+34.5=1826.2 If 20 tons of ice cubes are produced per day, the direct cooling block ice machine will save cost than the salt water block ice machine if it is calculated as 8 months of production per year: (1826.2-1340)*30*8=116688 yuan The direct cooling block ice machine saves per ton of ice than the salt water block ice machine: (1826.2-1340)/20=24.3 yuan
